Arreguín became a target of the far right after he sent out some tweets on Feb. 1, hours before Yiannopoulos was scheduled to speak at UC Berkeley. Arreguín tweeted: “Bigotry is unacceptable. Hate speech isn’t welcome in our community.”

On Feb. 2, after a group of black-clad rioters protesting again Yiannopoulos had caused approximately $500,000 in damage downtown, and another $100,000 worth of damage to the UC campus, Arreguín put out a statement calling Yiannopoulos “a white nationalist.” Arreguín later retracted that characterization and changed it to “alt-rightist.” He apologized for his use of language.
